摘要
介绍了对象约束语言OCL(OB JECT CONSTRA IN T LANGUAGE)的概念、特性,分析了OCL元模型与UM L元模型间的关系,在此基础上对OCL在M DA(M ODE L DRIVEN ARCH ITECTURE)模型转换中的应用进行了研究,指出OCL存在的问题,并对OCL的研究方向提出了几点建议。
This paper describes the concept and characteristics of Object Constraint Language, and analyzes the relationship between the meta-model of OCL and UML. Based on this, its application to model transformation of MDA is also discussed. Then, the problems of OCL are pointed out. Finally, several suggestions of OCL are presented.
